Technical Field

[0001] The present invention relates to the technical field of conveying equipment, and in particular to a conveying device with a heat exchange function. Background Art

[0002] Conveying devices are used to transport materials from one location to another. They usually have a simple function. In some special applications, by adding modules with specific functions, the conveying device can achieve certain specific functions while conveying materials. For example, adding a weighing module can give the conveying device a precise metering function. This type of device basically includes a shell, material inlet and outlet, spiral conveying guide vanes arranged in the shell, and a shaft for fixing the guide vanes and a bearing for fixing the guide vane shaft.

[0003] At present, conveying devices are used in some special applications. For example, in some applications, high-temperature materials need to be cooled during transportation, and the materials to be processed need to be heated and dehydrated.

The heat taken away by the cooling water causes the water to heat up, and additional energy is required to cool the circulating water. The comprehensive energy consumption is generally high. Moreover, when the moisture content of the materials to be processed is high, directly sending them to the heating equipment for processing will increase the equipment load and greatly increase the heating power.

Low-temperature materials are introduced into the inner cavity of the outer cylinder 1 through the feed port 3, and high-temperature materials are introduced into the inner cavity of the transfer mechanism 4. After the low-temperature materials enter the outer cylinder 1, they are located on the outside of the transfer mechanism 4, so that the heat of the high-temperature materials in the inner cavity of the transfer mechanism 4 is transferred to the low-temperature materials, thereby performing heat exchange treatment, which is convenient for cooling the high-temperature materials that need to be cooled after heat transfer, and the low-temperature materials that need to be heated and dehydrated receive the heat transferred by the high-temperature materials, heat the low-temperature materials, thereby heating and dehydrating them, and the water vapor is discharged through the exhaust port 11, and the low-temperature materials after heating and dehydration are discharged from the discharge port 10, which is convenient for effectively achieving the heat exchange treatment effect during the transportation process.

[0018] The outer side of the outer cylinder 1 is sleeved with an insulation sleeve 14, which is made of silicate sepiolite composite insulation material. The insulation sleeve 14 made of silicate sepiolite composite insulation material has the effect of heat insulation and heat preservation on the outer cylinder 1, preventing the heat transferred from the high-temperature material to the low-temperature material from being quickly transferred and dissipated, affecting the heating and dehydration effect of the low-temperature material.

[0019] Reference Figure 6-7As shown, a first sprocket 8 is installed on the outside of the discharge cylinder 7, and a driving mechanism 9 is engaged with the outside of the first sprocket 8. The driving mechanism 9 includes a transmission chain 94 engaged with the first sprocket 8, and the inner cavity of the transmission chain 94 is also engaged with a second sprocket 93. A base 91 is provided below the outer cylinder 1, and a reduction motor 92 is installed on the upper end of the base 91. The second sprocket 93 is installed on the outside of the output end of the reduction motor 92.

[0020] The switch of the reduction motor 92 is started by an external switch, and the output end of the reduction motor 92 drives the second sprocket 93 to rotate, and the second sprocket 93 drives the first sprocket 8 meshing with it to rotate, and the first sprocket 8 drives the other meshed first sprocket 8 in its inner cavity to rotate, and the first sprocket 8 drives the discharge barrel 7 and the material transfer mechanism 4 to rotate, so as to facilitate the material transportation by the material transfer mechanism 4.

[0021] Reference Figure 1-5 As shown, the inner cavity of the outer cylinder 1 is movably provided with a material transfer mechanism 4, both ends of the material transfer mechanism 4 pass through the outer cylinder 1 and extend to its outside, the two sides of the outer cylinder 1 are respectively screwed with a left sealing end cover 15 and a right sealing end cover 16, the left sealing end cover 15 and the right sealing end cover 16 are movably sleeved on the outside of the material transfer mechanism 4, the left end of the material transfer mechanism 4 is screwed with a discharge cylinder 7, the material transfer mechanism 4 includes a rotating cylinder 41 screwed with the discharge cylinder 7, the outer side of the rotating cylinder 41 is equidistantly installed with outer spiral pieces 43, the outer spiral pieces 43 match the size of the inner cavity of the outer cylinder 1, the inner cavity of the rotating cylinder 41 is equidistantly installed with inner spiral pieces 42, the right end of the rotating cylinder 41 is rotatably connected to the fixed rotating component 5, and the right end of the fixed rotating component 5 is connected to the feed elbow pipe 6.

During the flow process, the high-temperature medium (high-temperature material) is cooled, and the temperature of the low-temperature medium (low-temperature material) rises due to the absorption of heat, thereby heating and dehydrating the low-temperature material. At the same time, the inner spiral sheets 42 and the outer spiral sheets 43 also have the function of increasing the heat exchange area, thereby improving the heat exchange efficiency.

An annular groove 57 is provided on the left side of the fixed disk 51, and the right side of the rotating drum 41 is integrally connected to the annular clamping ring 44, which is movably connected to the inner cavity of the annular groove 57. A sealing groove 56 is provided on the left side of the fixed disk 51, and a sealing gasket 58 is connected to the inner cavity of the sealing groove 56. The left side of the sealing gasket 58 fits with the right side of the rotating drum 41, and the sealing gasket 58 is made of high-temperature resistant rubber material.

[0024] By designing a fixed rotating component 5 between the feed elbow pipe 6 and the drum 41, when the drum 41 rotates, the right side of the drum 41 rotates in the inner cavity of the mounting groove 55 on the left side of the fixed disk 51, and the fixed disk 51 and the sleeve disk 52 are screwed and fixed by the fixing bolts 53 and the fixing nuts 54, so that when the drum 41 rotates, the feed elbow pipe 6 can stably transport materials without rotating therewith, and the right side of the drum 41 is limited to rotate in the inner cavity of the annular groove 57 on the left side of the fixed disk 51 by the annular retaining ring 44, which effectively improves the rotation stability of the drum 41, and by sleeve-fitting the sealing gasket 58 in the inner cavity of the sealing groove 56 on the left side of the fixed disk 51, it is convenient to effectively increase the sealing of the connection between the feed elbow pipe 6 and the drum 41, avoid the discharge of hot air from the gap, and effectively improve the thermal insulation effect.
